Abstract
The first synthetic route of novel 4'-cyclopropylated carbovir analgues is described. The construction of cyclopropylated quaternary carbon at 4'-position of carbocyclic nucleosides was successfully made via sequential Johnson's orthoester rearrangement and ring-closing metathesis (RCM) starting from ethyl glycolate. Synthesized compounds 15 and 16 showed moderate antiviral activity without any cytotoxicity up to 100 micromol.
